I guess the effort is strictly to make things easier to fix and modify, that is good.
I am now a Mate user, after I was kinda forced to drop Gnome2, which I understand was also a real bear to maintain.
Wayland website says "Wayland is intended as a simpler replacement for X, easier to develop and maintain." ... maybe the Gnome people know something about that, but they sure don't understand how to relate to their client base.
